Description: Access control techniques are methods used to restrict access to systems and data based on user roles. In the context of Zero Trust security, these techniques focus on the premise that no entity, whether internal or external, should be trusted by default. This means that every access request must be verified and authenticated, regardless of its origin. Access control techniques in this model include multi-factor authentication, network segmentation, and identity and access management (IAM). These practices ensure that only authorized users can access specific resources, thereby minimizing the risk of security breaches. Implementing these techniques is crucial in various environments, including cloud computing, where data can be more vulnerable to attacks due to its distributed nature. By adopting a Zero Trust approach, organizations can strengthen their security posture, ensuring that every access is evaluated in real-time and that appropriate security policies are applied to protect sensitive information.
